LODded, converted, committed. Certainly the toughest one I've ever converted; the turrets and thrusters weren't exactly trivial to get to look and work right.
As for the turrets: you can choose whether to let the gunners fire at will or whether to fire them forward manually. You choose by selecting one of the two available primaries; if you have the "gunner control" primary selected then the gunners will operate the turrets, or if you switch to the "manual control" primary, the turrets will reset to pointing forward and you can fire them with your primary trigger. I'm going to also look into whether it's feasible to add fake comms menu entries for the gunners so you can actually easily tell them to, for example, fire on a specific target.
